They're worth every penny.  I've installed them on many aircraft with excellent results. 

Considering that failure of the fluid filled dampers is a slow process and that a failing shimmy damper makes the rest of the components in the nose gear wear out at an accelerated rate the Lord shimmy damper is a cost effective replacement. 

If you're operating in winter conditions it is almost a  must.

I just purchased new O rings for my C-182 old Shimmy Damper and plan to replace them. $5 overhaul and it looks very easy. To open the damper, Do not try to pry it open, just put some air pressure in the oil filler hole and the unit is supposed to pop apart.

The part numbers you are referring to are: AN6227"B"6 and "B"18, these part numbers cross referrence to MS28775-011 and MS28775-213 respectively. These can be had from AC Spruce or any local aircraft parts supplier cheap.

Does anyone have a diagram of the Cessna shimmy dampner for the 150?
I found one for the Beachcraft but it looks different.
Mine only has one large "O" ring on the first forward plate and none on the inside plunger. It does have one small one at the back end where the shaft goes out. Is there an "O" ring inside the first or second round plunger?
Thanks,

Glenn
